O However,

Answer 1

The word or phrase that should be added to clarify the relationship between the first and second sentences is 'For example'.

Step-by-step explanation:

For example,

when we say 'for example' we introduce additional information that supports or provides evidence for the previous statement or claim. In this case, adding 'For example' before the second sentence would clarify that the information about smoking doubling or quadrupling the risk of coronary heart disease is an example of the research that has proven smoking is bad for your health.

Therefore, the correct word or phrase that should be added to clarify the relationship between the first and second sentences is 'For example'.
